Mary Polly Akin Renfro/Bearden

Looking for the name of Mary Polly Akin's first husband, Renfro. Mary polly was D/O William C. Akin B: 1786 Ky., and he married Rebecca McKinney 1812, Lincoln Ky. Mary Polly had 4 children by ?Renfro, Rebecca, Sarah (Sally), James A. and John Mark Renfro/Renfrow. John Mark would be my gggrandfather, B:1847 Lafayette Ark., D: 1932 Ok. He married Rebecca DAY Renfro, whose mother was Sarah Tollet AKIN Day, so they were 1st cousins, not uncommon in those days. Hoping to find any help, as this has become a brickwall for me.
